manim_express
Requirements
manimgl>=1.3.0
manim>=0.13.1
sparrow_tool

# helium
# pyperclip
Install
pip install manim_express
以上步骤将安装 manim_express 和 manimlib. 然后就可以在任何代码位置导入使用这个动画库了.
快速开始
-
渲染一个动画: 3b1b:SquareToCircle
from manimlib import * from manim_express import EagerModeScene scene = EagerModeScene() circle = Circle() circle.set_fill(BLUE, opacity=0.5) circle.set_stroke(BLUE_E, width=4) square = Square() scene.play(ShowCreation(square)) scene.play(ReplacementTransform(square, circle)) scene.hold_on()
与渲染画面交互:
- 按住
d键 或 鼠标左键 然后移动鼠标可以改变三维空间中相机的旋转视角. - 按住
s键 或 鼠标右键 然后移动鼠标可以平移相机. - 按住
z键 或 ctrl键 同时滚动鼠标滚轮以缩放画面. - 通过
r重制相机视角. - 离开/退出当前动画:
qortab - 暂停动画:
spaceorctrl - 前一段动画:
LEFT - 后一段动画:
RIGHT - 重新播放当前动画:
DOWN
- 按住
-
manim_expressvsMatplotlib:
在某些情况你需要安装LaTeX 以渲染tex字体.
幸运的是manim_express中提供了在线的latex 编译选项. 通过设置SceneArgs.use_online_tex=True进行激活.from manimlib import * from manim_express import * import numpy as np CONFIG.use_online_tex = True # Use online latex compiler theta = np.linspace(0, 2*np.pi, 200) x = np.cos(theta) y = np.sin(theta) # matplotlib # import matplotlib.pyplot as plt # plt.plot(x, y, color='green', linewidth=2) # plt.axis("equal") # plt.show() # manim_express scene = EagerModeScene() scene.plot(x, y, color=GREEN, width=2, scale_ratio=1) scene.show_plot() scene.hold_on()
